a live one
1. A person who lives a wild, carefree, or spendthrift life. I hear Tommy's dating a real live one these days.
2. A person targeted to be the victim of a scam or to be made a dupe by others. Don't go wandering wide-eyed in this part of town—crooks around here can spot a live one a mile away.
